CTK0* WIRING

NOTE: Refer to section Electrical Connections - High Voltage Connections for 208/230 volt line connections to the air conditioner

or heat pump.

NOTE: A removable plug connector is provided with the control to make thermostat wire connections. This plug may be

removed, wire connections made to the plug, and replaced. It is strongly recommended that you do not connect multiple wires

into a single terminal. Wire nuts are recommended to ensure one wire is used for each terminal. Failure to do so may result in

intermittent operation.

Typical 18 AWG thermostat wire may be used to wire the system components. However, communications reliability may be

improved by using a high quality, shielded, twisted pair cable for the data transmission lines. In either case, 150 feet is the

maximum length of wire between indoor unit and outdoor unit, or between

indoor unit and thermostat.

FOUR-WIRE I NDOOR AND OUTDOOR W IRING

Typical wiring will consist of 4 wires between the indoor unit and outdoor

unit and between the indoor unit and thermostat. The required wires are: (a)

data lines, 1 and 2; (b) thermostat “R” (24 VAC hot) and “C” (24 VAC com-

mon).

TWO-WIRE OUTDOOR, FOUR-WIRE INDOOR W IRING

Two wires only may be utilized between the indoor and out-

door units. For this wiring scheme, only the data lines, 1

and 2, are required between the indoor and outdoor units. A

40VA, 208/230 VAC to 24 VAC transformer must be installed

in the outdoor unit to provide 24 VAC power to the outdoor

unit’s electronic control. CTK0* manual will state if this trans-

former is optional or mandatory. Four wires are required be-

tween the indoor unit and thermostat.

NOTE: Use of the CTK0* transformer is recommended if

installing a dual fuel system. Failure to use the transformer

in the outdoor unit could result in over loading of the furnace

transformer.

COMFORTNET™ SYSTEM ADVANCED F EATURES

The ComfortNet system permits access to additional sys-

tem information, advanced setup features, and advanced di-

agnostic/troubleshooting features. These advanced features are organized into a menu structure. See thermostat installation

manual for directions on how to access the ComfortNet User Menus. See following tables for menu layout.

CONFIGURATION

The configuration menu provides functional information about the installed equipment. System tonnage and number of cooling

and heating stages are displayed within this menu. A tonnage check will help determine if the equipment shared data is correct

for the unit. If the tonnage is not correct, even though very rare, a memory card is available to load the proper data.

DIAGNOSTICS

Accessing the air conditioner/heat pump’s diagnostics menu provides ready access to the last six faults detected by the air

conditioner/heat pump. Faults are stored most recent to least recent. Any consecutively repeated fault is stored a maximum

of three times. Example: The power supply to the air conditioner/heat pump is continuously below 187 VAC. The control will

only store this fault the first three consecutive times the fault occurs.

NOTE: It is highly recommended that the fault history be cleared after performing maintenance or servicing the heat pump.
